Diesel vs gas for Class A....also length of RV....

Please NO hate Post over this, it's just my humble expierence. Better mpg on DP vs Gas, yes. I've had both. Take in extra purchase cost, maintenence and then cost of repairs. Yes, both break. It's a motor, they break and need repairs. DP are way more expensive to maintain and repair. I'll go up the hills slower, not in a hurry anyway. This poor boys expierence is a DP isn't worth the extra cost.
